TRANSPORTER.

Application tiled August 13, 1926, Serial No. 129,057, and in France March 9, 1926.

The present invention relates to transmission systems in which two or more parallel iieXible members are connected together at intervals by cross-ties which engage with notched wheels.

According to this invention, the Said connecting cross-ties are utilized as supporting or carrying members for the elements ot' a transporter.

By reason oi the lightness ot a` transmission of the type employed, the transporter can be very widely developed. Moreover, this transmission lends itsclt to changes of direction in the three dimensions of space, which fact is of great value in its application to transporting devices.

For example, it' thc Hight ot cables is arranged in a vertical plane tor a certain part ot their travel, the connecting ties then coming into engagement with horizontal wheels, it it is desired to change the level or to incline the transmission cables, it is only necessary to bring the flight into a horizontal position by twisting' it and to engage the crossties with the notches ot' a vertical wheel.

As a result, however, the cross-ties, which were originally vertical, now assume the horizontal position. Consequently it is usually necessary to adopt, special means in order that the transporter elements shall not participate in the oscillatory movements of the cross-ties when the latter are utilized for supporting or carrying' these elements, according to the present invention.

The annexed drawings representby way of examples suitable forms of construction of a transporter according to the invention.

Figure l shows in perspective one of the elements of an overhead monorail transporter.

Figure 2 is a similar view ot a transporter running upon a bottom rail.

Figure 3 represents diagrammatically and in part longitudinal elevation a transporter ol' the truck type.

Figure 4 is a. 'front view ot one element ot a transporter in which the. flight of cables is horizontal.

Figures 5 to 'i' are partial elevations, relating to a pivoted suspension iitted to a connecting cross-tie.

Figure S is a view in cross section on the line 8 8 of Figure 7.

Figures 9 to 11 show the application to a continuous furnace of a device similar to that of Figure 2.

Figure 9 is an elevation ot one otl the i'urnace heads.

Figure 1() is a corresi'ionding plan.

Figure 11 is a transverse section of Figure l() upon the planc 11-'11 and on ay larger scale. Y

According to Figure 1, each connecting member or cross tie 1, carries at its base a hook 2, and at the, top a` cranked arm 3 terminating in a horizontal `journal Ytor a, tlanged wheel 4, which runs upon an overhead rail Each member 1 is connected to the adjacent ones in t'ront and rear by cable lengths G secured to the member 1 by any suitable means.

According to Figure 2, each connecting member or cross-tie 1 is surmountcd by ay tray or plate 7 and provided at its base with a pivotal fork for a flanged roller 4 running` upon a bottom rail 8. A roller 8a, mounted treely upon the upper extension of the member 1` travels between two guides 8" which maintain the tray in horizontal position. This arrangement is especially applicable to continuous furnaces, stoves and drying apparatus.

ln Figure 3, the transporter is formed by a. line of trucks 9, running upon an elevated rail l0. Each of these trucls is driven by one of the connecting ties 1, the extended upper end of which enters a socket 1l titted to the bottom ot the platform ot each trucl.

According to Figure 4, the connecting members are arranged horizmitally. ollers 8', rotatably mounted on the cross-ties, run upon rails 8d. Each member 1 carries suitable means such as hooks Se from which the load is suspended.

The pivotal suspension device to which Figures 5 to 8 refer, is more, especially intended for use in transporters involving changes of level or inclination.

In this device, a ring 12 is mounted loosely about the middle ot the conm-cting member or cross tie 1. This ring carries two diametrically opposite trunnions upon which a small frame, 13 is pivoted. This framel is also provided with two trunnions alined in a direction perpendicular to the axis oi' the trunnions for the ring 12. Upon the trunnions of the frame 13 there is pivoted a forked member 14 having its arms cranked at right angles, its stem carrying a roller 15 adapted to run upon a suspended rail 16. The stem of the fork 14 also 'l'orms at its lower end a hook or ring which serves. tor example, for the suspension of a pan or vessel, the center of gravity of the whole when empty being at or preferably below the level of the head of the rail 16.

As a result of this arrangement, the stem ot the fork 1l remains constantly vertical, whatever be they position assumed by the connecting member 1 during the changes ot level or of inclination, and oscillzttions of the suspended pan or the like are avoided.

In the application illustrated in Figures 9 to l1. the transporter is formed by a series ot elements T, each carried by two cylindrical pins or rods 1 located at the middle ot its width and near its ends. At the base of each rod t there is attached by a vertical pivot the supporting arm or cheek-piece. et Fig. 11) of a roller t mounted upon a horizontal journal. The rollers t otl all the elements run upon one ot the flanges ot a channel beam tw, which is carried by a training 1T and extends over the entire closed path ot the elcments. These same rollers are provided with tianges to prevent them becoming derailed and ensure their turning to follow the track at curves.

Near its upper end, each rod 1 carries a roller a mounted loosely upon it. This roller runs between two guide bars 8b fixed to the training 17. like the rail 8, and following the circuit ot the latter.

The rods 1 are spaced unil'ormly along the rail S, each being attached to the next one by two or more superposed lengths of cable (i. The spacing apart of the cables varies from one pair ot' supporting rods to the next, in suchV a way that the successive lengths which meet at each support have their en'ds placed .side by side. 'Each of the cable lengths extends b \yond the support to which it is connected, and it is secured only on the tar side ot the axis of the support to a connecting member t3 fitted to this support.

The supporting rods 1 engage with notches 1S provided for the purpose upon the rim ot the wheel 1S revolving upon the vertical shaft 19 carried by a trame 2t). The wheel 1S. around which the change of direction o the transporter takes place, is tast with a toothed wheel 21, meshing with a pinion 22 keyed upon the final shaft of a speed reducing gear 23 driven by a motor 24. The other head of the transporter comprises a second wheel similar to 1S.

Between the two Wheels, one of the lines of elements 7 passes through the tunnel furnace with which said transverse members engage,

transporting elements connected to said transverse members, and rollers carried by said transverse members and an elevated rail- 'ay on which said rollers roll.

2. In a transporter, a plurality of parallel flexible cables. transverse members connect- I mg said cables at intervals, notched wheels with which thc said transverse members engage. transporting elements connected to said transverse members, rollers carried b v said transverse members and a bottom railway upon which said rollers roll.

2%. In a transporter, a plurality of parallel flexible cables, transverse members connecting said cables at intervals, notched wheels with which the said transverse members engage` transporting elements connected to said transverse members, rollers guided by said transverse members, a railway upon which said rollers roll, a roller freely mounted on each connecting member and two parallel rails between which the said roller rotates.

4. In a transporter, a plurality ot parallel flexible cables, transverse members connecting said cables at intervals, notched wheels with which the said transverse members engage, transporting elements and jointed means tor connecting said elements to said transverse connecting member.

In a transporter', a plurality of' parallel flexible cables, transverse pieces connecting the said cables at intervals, notched wheels with which the said transverse pieces mesh, transporting elements, and means jointed in a plurality of directions for connecting said elements to said connecting pieces.

In testimony whereof I have signed my name to this specification.
